Epibenthos and demersal fish monitoring in function of dredge disposal monitoring

Epibenthos and demersal fish monitoring at long-term monitoring stations Trawl samples were taken within the disposal site and outside the disposal site (close neigbourhood) (classic controle/impact design). Sampling activities were in February-March and in September/October. A 8 meter shrimp beam trawl (22 mm mesh in the cod end) equipped with a bolder chain was used.The net was towed during 30 or 15 minutes at an average speed of 4 knots.

Epibenthos and demersal fish monitoring in function of wind energy development. Trawl samples were taken within the wind farms (between the turbine rows, just outside the edges of the concessions and at reference stations

This dataset contains individual counts of fish species sampled in the seagrass beds and mangrove creeks of Gazi Bay (10 locations, 41 species) on 17 and 19 July 1996. Sampling was carried out using a beam trawl (fine mesh: 6mm width). The data were digitized by VLIZ from the original report: Dethier, K. (1997).
